So it looks like I have a 390 bored .40 is that possible

[96 jag ranger]

Or do I have a 410 bored .40

410 is a Mercury only engine. It’s the same bore as a 360 or 390. The displacement difference in 360/390/410 comes from the stroke.

Ford did use 410 pistons in 390 truck motors to achieve the low compression some of them actually said 410 near the pin. The 410 pistons with 390 stroke are below deck, that’s why truck compression is so low.

C8AE-H heads were very common on trucks and your exhaust manifolds will work fine since that’s how Ford did it.

Your intake casting number is incomplete but as long as it isn’t a cobra jet, low riser, high riser or some exotic race piece it’ll work fine too, in fact CJ or low riser will work with the correct gasket, but there will be an undesirable port mis match. I kinda suspect you have a fairly common “S” intake.

If you do in fact have a 410/428 crank you will need the corresponding flex plate unless someone has internally balanced it with heavy metal…

Fel Pro FS 8554 PT has all the gaskets you should need. Buy the prior mentioned books and you should be in business…

I can’t help you with the distributor - what you’re saying doesn’t make any sense, but you’ve got that figured out.

Actually a lot of what you’re saying makes no sense. If the intake is an S intake just put the thing together it’ll work fine. And stop making the head gaskets harder than they need to be. In fact you’re making it all harder than it needs to be.

Based on the 1U crank, should be a 410 which at forty over is going to actually be 417 or something close.

I hope whoever build the bottom end knew what they were doing.

I almost hate to open this can of worms, but do you know what cam is in it?

This motor was built for towing a three axle pontoon boat in Shasta california.dont know what cam is motor any good or just scrap .so you said that I need a special intake gasket as for the part number you gave me its not correct . summit has a gasket set that is 4 330 .will it work as my bore is 4.090.im not good with number not trying to be a pita . thanks for the help

[96 jag ranger]

It has h beam rods at least that is what it looks like.

[96 jag ranger]

So which head gasket cometic 4.165 or 4.330

[96 jag ranger]

The dist issue is the ft dist is with the oring on is 1.98 and the dist hole in the intake is 2.00.i don't know what a regular Fe dist measure is .

[96 jag ranger]

These are the parts that I have to work with.im not trying to make it harder .

[96 jag ranger]

So as far as I can figure out I have a 67 mercury 410 bored out .40. with a ft intake and a ft dist and a ft oil pump shaft and a ft oil pump.ok I can live with that . sounds strange to me but that's ford . thanks for the information..have a good day.

I’ve got more but it’ll have to wait a bit.

I don't believe this was done in this manner by Ford. I am pretty certain you have a Frankenstein engine/trans setup made from a PO(s).

[DuckRyder]

You’re all over the place, didn’t you say it was an S intake?

Also, when you say H beam rods, do you mean non factory rods?

[96 jag ranger]

Ford performance rods with a mercomatic trans .

[96 jag ranger]

I mean cobra jet rods
